PARAFFINJVIYACHINE.

Specification of Letters Patent.

Patented F eb. 22,' 1 9i t5.

Application led February 27, 1915. Serial No. 11,076.

To ZZ lwhom t may concern.'

Be it known that I. Besen D. GRIFFITH, a citizen of the United States` and residing at Mason City, in the county of Cerro Gordo and State of Iowa, have invented certain new and useful Improvements in Pai-affin- Machines, of which the following is a specification.

This invention relates to machines for applying paraffin to the interior of pails or other vessels, and its primary object is to provide a device ot this character by means of which the parailin is melted or liquefied by the action ofstcam and also directed into and sprayed against the interior of the vessel being treated.

The construction ot' the improvement will be fully described hereinafter in connection with the accompanying drawing which constitutes a part of this specication, and its novel features will be set forth and defined in the appended claims.

In the drawing: Figure l is a front elevation of one form 'of the improved apparatus, the same being what may be termed al double construction, employing two independent parall'in reservoirs, and Fig. 2 is a central vertical sectional view ,illustrating a single paraffin reservoir or receptacle.

The reference numeral 1 designates a cylindrical or tubular member provided with a base 2 adapted to be secured by suitable means as screws 23 to a floor. 'lo the upper end of the tubular member -l is connected by means ot a T-coupling l, a cylindrical parallin reservoir or receptatdeI 5 having au open lower end (3 and terminating at its upper end in a spray nozzle 7 suitably per lol'ated as shown. The upper portion of the Ireservoir 5 immediately below the nozzle 7 is of conical form as shown atb and this conical portion is'l'ormed with a plurality holder 12 is provided with a central opening through which the conical upper end ol the parallin reservoir 5 projects and said holder is supported upon the [lange 1l ot the collar 10 as clearly shown in Fig. 2. The pail or other vessel 15 is supported in inverted position as shown in Fig. 2 upon the holder 12.

Communicating with the nozzle 7 of the paraltin reservoir is a tube 16 open at its lower end and connected by a coupling 17 to an elbow 18 having connection with a steam inlet pipe 19 controlled by a valve Q0.

The utility and operation of the apparatus constructed as above described will be readily understood. Parafti'n is supplied to 'the `space within the cylindrical member i and the reservoir 5 afford means for escape for f surplus liquid paraliin, directing it back as illustrated in Fig. 2, to the reservoir.

I preferably provide the parallin holder i with a drainpipe 4 equipped with a valve stl to draw ofi' the contents of the member 4 when desired.

'Vhat I claim as new is:-

1. In a, parallin machine, the combination withl a base si 1pport, ot' a hollow receptacle or container lor parallin open at its lower end and terminating at its upper end in a discharge nozzle, ot' a tubular connection between the lower open end ot' said reservoir and base adapted to contain parallin, a tubular member within said reservoir or container, and a steam supply pipe connected to the lower end oi said tubular member.

2. ln a parallin machine, the combination with a supporting base, of a parallin reser-v voir open at its lower end, a hollow `coupling between the lower end ot said reservoir and base, a spray nozzle at the upper end ot said reservoir, a tubular member within said reservolr open at its lower end and communi-- rating at its upper end with said;nozzle, and a steam supply pipe connected with the lower end ot' said tubular member, said res ervoir being l'ormed with openings adjacent to its upper end for the return of surplus parallin to the reservoir.

n a paraffin machine, the comhiation a cylindrical member connected to the owe end of said reservoir and adapted. $0 conm-,n paraffin, ay tubular member wthm, Saad resem Voir, a steam supply pipe eonnecev o h lower end of said tubuiar member, e "Vessel holder mounted upon the upper poron o said resevor having an annui.v ing' ange. end Hzfanged cozuf K upon the upper end of said reservoir.

n testimony whereof ax my sgmfgure in presence of two witnesses.
